Winter maintenance

[TeenaTeens]

Just back from a few weeks abroad, and these are my readings. I’m not sure if I need to mess with this as the CSI is fine. I’ve turned of the chlorinator for now, but my CYA is usually around 60, I keep my TA at 60 and Ph around 7.8-8.0 during Florida summer months and water temp at 88-89 as well. Is it ok to just let these numbers stay as is during the winter months?

Lower the pH into the 7’s.

I don’t understand - that will put my csi out of range. Can you explain for me please?

That would a due to low water temperature. Always best to keep pH in the 7’s. I doubt your CSI will go below. -0.6.

Add enough to MA to bring your pH to ~7.8

That will give you a CSI of -0.17, which is perfect.
